Most water filter pitchers are made of BPA-free plastic. But as new research shows that bottled-water drinkers ingest tens of thousands of excess microplastic particles, wellness lovers have begun to look askance at water filters that are themselves made of plastic.
In the nineteenth century, entire railway networks became obsolete almost overnight, not due to physical deterioration, but because of changes in the technical standards that supported them. The expansion of railroads across Europe and North America adopted different track gauges, and as a dominant standard gradually emerged, these infrastructures became incompatible with one another.
MVHR (Mechanical Ventilation with Heat Recovery) systems are designed to continuously replace stale indoor air with fresh outdoor air while recovering heat that would otherwise be lost. In commercial and residential buildings, this technology provides several important advantages. First, it allows buildings to remain energy efficient without sacrificing airflow.
Checking your equipment once a month helps catch small issues before they turn into expensive repairs. A routine keeps everything running smoothly and extends the life of the hardware. Managers should create a simple checklist for their maintenance staff to follow.
Heating, cooling, and battery temperature control are among the biggest energy consumers in electric buses today - and thus have a direct impact on range, availability, and operating costs.
We are making sure that we have renewable energy powering all of our datacentre footprint. We have 100% renewable power today that is powering all of Azure, and we're very proud to build that base and essentially stimulate renewable energy around the world and in the UK.
Heritage is usually catalogued by what can be drawn, not by what changed temperature. In heat, buildings are learned first through skin, only later through sight. Generations learn, through their bodies, what works. Shade reduces glare and radiant heat. Air movement shifts perception by several degrees. Thick walls slow temperature swings.
Photovoltaic (PV) solar energy represents a modular technology that can be manufactured in large-scale facilities, generating economies of scale, while also being adaptable to small-scale applications. From residential rooftop systems to large-scale power generation installations, photovoltaic solar energy has established itself as a cost-effective option for electricity production in many countries around the world.
Ammonia might be the world's most under appreciated chemical. Without it, crops would go unfertilized and billions of people would starve. Humans started making ammonia in large amounts just over a century ago, and since then the process used to make it, known as Haber-Bosch, hasn't changed much. A new startup, Ammobia, says that it has tweaked the Haber-Bosch process to lower the cost by up to 40%.
They do nothing to save you power Scam "power saving" devices are rampant online. These devices plug into an outlet and promise to "improve the use of energy," "extend the life of electrical equipment," and even "avoid illegal electrical waste." Sounds great, right? Also: This USB power meter I tested is shockingly accurate - especially for how cheap it is Well, despite the bold claims and the sticker on the front of the unit, they are too good to be true.
Sometimes I'm rather impressed by the ingenuity of those in the business of making scammy gadgets. Over the years, I've examined a wide range of products, from scam devices that claim to save you money on your power bill to a high-power USB charger filled with an unusual goo-like substance. Also: Want to cut your electric bill? Skip these scam 'power-saving' devices - and buy this instead
You should buy a dehumidifier. It will almost certainly improve your home environment. Pulling moisture from the air helps banish condensation and mold, making it cheaper and easier to regulate the temperature in your house or apartment. There's a reason the chatter about dehumidifiers has grown so loud and sales are soaring; it's because they work. Whether you've seen a persuasive Reddit thread, a life hack on TikTok, or an expert guide to the best dehumidifiers, the hype is real.
The purpose of a humidifier is to increase and regulate the indoor air's moisture level. How this works is different depending on the season and temperature both inside and outside. Overall, though, a humidifier helps maintain a comfortable, healthy, and optimal humidity range of 30 to 50%. To create this environment, most humidifiers use water vapor or steam to help combat dryness caused by heating systems or harsh climates (which often happen indoors during winter).
The US is now leading a global surge in new gas power plants being built in large part to satisfy growing energy demand for data centers. And more gas means more planet-heating pollution. Gas-fired power generation in development globally rose by 31 percent in 2025. Almost a quarter of that added capacity is slated for the US, which has surpassed China with the biggest increase of any country.
